[0006]

By the way, in order to provide many functions without deteriorating the portability, which is an advantage of the portable terminal device, it is desirable to reduce redundant parts as much as possible.

However, according to the conventional portable telephone device, since the volume of the call sound is smaller than that of the ring tone, speakers must be separately provided for the call sound and the ring tone. There is a problem that reduction in manufacturing cost is hindered. Moreover, since high quality sound quality is required to make the ringtone a melody, a speaker for the ringtone needs to have the same performance and size as the speaker for the call sound, further increasing the manufacturing cost, Due to the increase in the occupancy of the housing surface, the display unit and the operation unit are reduced in size, which hinders convenience.

[0008] Therefore, in order to solve the above-mentioned problems, an object of the present invention is to provide a portable terminal device capable of reducing the manufacturing cost of the device and improving the convenience.

FIG. 3 is a block diagram showing an example of the internal configuration of the portable telephone device 100. As shown in FIG. 3, the mobile phone device 100 is, for example, a CPU (Central Processing Uniform).
t) 41, a transmission / reception processing unit 51, a ring tone generator 52, a voice demodulator 53, and a switching control unit 5 including switches 55 and 56.
4, an amplification gain control unit 57, a speaker amplifier 58, and a speaker 15. The input tool 20, the transmission / reception processing unit 51, the switches 55 and 56, and the amplification gain control unit 57 are connected to the CPU 41.

The CPU 41 controls the transmission / reception processing unit 51, the switching control unit 54, and the amplification gain control unit 57 based on the operation of the input tool 20. The antenna 12, a ring tone generator 52 and a voice demodulator 53 are connected to the transmission / reception processing unit 51. The transmission / reception processing unit 51 transmits / receives an incoming signal, a voice signal, and various other signals (such as a signal indicating character information and image information) to and from a base station (not shown) via the antenna 12. The transmission / reception processing unit 51 notifies the ring tone generator 52 and the CPU 41 that the incoming signal has been received.

The CPU 41 controls the transmission / reception processing unit 51 to receive a voice signal when the user (operator) presses the call key 31 during reception of an incoming call signal. Further, when the end key 32 is pressed by the user during reception of the audio signal, the CPU 41 controls the transmission / reception processing unit 51 to cut off the reception of the audio signal.

The ring tone generator 52 includes a switching control unit 54.
Of the transmission and reception processing unit 5
While being notified of the reception of the incoming signal from the communication device 1, a ring tone signal such as an alarm sound or a melody sound is generated and a switch 55 is generated.
Output to The transmission / reception processing unit 51 outputs the received audio signal to the audio demodulator 53. The audio demodulator 53 is connected to one end of the switch 56 of the switching control unit 54, and demodulates an audio signal from the transmission / reception processing unit 51 and outputs the demodulated signal to the switch 56. The other ends of the switches 55 and 56 are connected to a speaker amplifier 58.

When the end key 32 is depressed, the CPU 41 turns on the switch 55 and turns off the switch 56, and controls the ring tone signal to be output to the speaker amplifier 58. When the call key 31 is depressed, the CPU 41 turns off the switch 55 and turns on the switch 56 to control the audio signal to be output to the speaker amplifier 58.

The speaker amplifier 58 is connected to an amplification gain control unit 57 and the speaker 15. The speaker amplifier 58 amplifies the signal (voice signal or ringtone signal) from the switching control unit 56 and outputs the amplified signal to the speaker 15.
The speaker 15 outputs a signal from the speaker amplifier 58 to the outside. The amplification gain control unit 57 controls the amplification gain when the speaker amplifier 58 amplifies the signal.

Then, at the time of standby, the CPU 41 controls the amplification gain control unit 57 so that the volume of the speaker 15 becomes a predetermined volume. Further, during a call, the CPU 41 controls the amplification gain control unit 57 so as to be lower than a predetermined volume of the speaker 15 at the time of standby.

The portable telephone device 100 has a drive amplifier 61 to which the vibration motor 16 is connected, and a microphone amplifier 62 to which the microphone 13 is connected. The drive amplifier 61 amplifies the operating power for operating the vibration motor 16 and is connected to the CPU 41. When receiving the incoming signal from the transmission / reception processing unit 51, the CPU 41 controls the drive amplifier 61 to operate the vibration motor 16 while the incoming signal is being received.

The microphone amplifier 62 is connected to the transmission / reception processing unit 51, and amplifies the audio signal from the microphone 13 and outputs the signal to the transmission / reception processing unit 51. In addition, based on the operation of the input tool 20, the CPU 41 can also finely adjust the volume of the ring tone, the volume of the voice, the vibration of the vibration motor 16, and the like. For example, C
The PU 41 controls the amplification gain control unit 57 so that the volume of the ringtone at the time of standby gradually increases (steps up) as time elapses. Note that the speaker 1
The CPU 41 for adjusting the volume of 5 is not limited to these, but may be any as long as it has the same effect.

Next, an operation example of the portable telephone device 100 will be described. FIG. 4 is a flowchart illustrating an operation example of the mobile phone device 100. Here, it is assumed that the processing of the CPU 41 is used as a reference. As shown in FIG.
First, in step A1, the mobile phone 100
Is determined by the CPU 41 on the basis of the call key 31 and the end key 32 pressed by the user (user) immediately before. If the key pressed immediately before is the end key 32, it is in the standby state and the process proceeds to step A2.

In step A2, the CPU 41 enters a standby state until the transmission / reception processing unit 51 receives an incoming signal from, for example, a base station. When the incoming signal is received, the process proceeds to step A3. At this time, the switch 55 is on and the switch 56 is off because of the standby state, and the ring tone generator 52 generates a ring tone signal of, for example, a melody sound set in advance by the user as a ring tone, and sends it to the speaker amplifier 58. Output.

In step A3, when the speaker amplifier 58 amplifies the ring tone signal, the amplification gain control section 57 is controlled by the CPU 41 so that a predetermined amplification gain is obtained, and the flow proceeds to step A4. Thereby, the speaker 15 outputs a ring tone signal at a predetermined volume. The predetermined volume is, for example, a volume at which a ring tone can be heard at a position where the speaker 15 is separated from the vicinity of the user's ear. In step A4, the CPU 41 waits until the call key 31 is pressed.
Proceed to.

In step A5, the switch 41 is turned off and the switch 56 is turned on by the CPU 41 in order to shift to the talking state, and the process proceeds to step A6. As a result, the transmission / reception processing unit 51 receives the audio signal, and the audio demodulator 53 demodulates the audio signal and outputs the demodulated audio signal to the speaker amplifier 58. In step A6, when the speaker amplifier 58 amplifies the audio signal from the audio demodulator 53, the amplification gain control unit 57 is controlled by the CPU 41 so that the amplification gain is lower than the amplification gain of the ring tone signal. Becomes

Thus, the speaker 15 can output sound at a volume lower than the ring tone. Thus,
When the user makes a call based on the incoming call notification by the ringing tone, the speaker 15 can be brought closer to the ear without anxiety by the ringing tone having a larger volume than the calling sound.

Here, in step A1, if the key pressed immediately before is the talk key 31, it is in a talk state and the process proceeds to step A7. At this time, the switch 55 is off and the switch 56 is on because of the call state. Step A
At 7, the CPU 4 waits until the user presses the end key 32.
When the end key 32 is depressed, the process proceeds to step A8. At step A8, the CPU 41 turns on the switch 55 and turns off the switch 56 in order to shift to the standby state, and ends.

In this way, the user can shift from the call state to the standby state, and since the volume of the ring tone during the standby is higher than that of the call sound, the notification of the incoming call can be reliably performed. Here, since the ringing volume is set so as to be stepped up, the safety is not impaired even when the speaker 15 is located near the user's ear during standby.

As described above, according to the portable telephone device 100 according to the embodiment, the standby key and the telephone key are operated by operating the call key 31 and the end key 32. The amplification gain control unit 57 for controlling the amplification gain of the signal output from the outside
The CPU 41 controls the amplification gain of the audio signal to be lower than the amplification gain of the ring tone signal in order to make the volume of the speaker 15 smaller at least during a call than at the time of standby. For this reason, the speaker can be used for both the ring tone and the call sound, so that the number of speakers can be reduced as compared with the conventional system in which speakers are individually provided for each application.

Accordingly, the manufacturing cost of the portable telephone device 100 can be reduced, and the occupancy of the speaker with respect to the housing surface can be reduced. Therefore, it is possible to increase the size of the display unit and the operation unit, thereby improving convenience.

[0037]

As described above, according to the present invention,
Volume control means for controlling the volume of the speaker based on the control division by the switching operation unit is provided, and this volume control means at least lowers the volume at the time of a call than at the time of standby.

With this configuration, the speaker can be used for both the ring tone and the call sound, so that the number of speakers can be reduced as compared with the conventional system in which speakers are individually provided for each application.

Accordingly, the manufacturing cost of the device can be reduced, and the occupancy of the speaker on the housing surface can be reduced, so that the display unit and the operation unit can be made large and the convenience can be improved.

The present invention is very suitably applied to a portable terminal device such as a portable telephone device having not only a call function but also an Internet use function.
